This is Photo Blend

Photo Blend 3D is uniquely designed software for photographers and scrapbookers to quickly combine parts of different photos into a new 2D photo montage or composition as well as to easily create 3D stereogram and anaglyph 3D images. Photo Blend will automatically adjust the lights and colors of the objects to visually snap into new composition even if the sources are very different. This goes as far as grabbing ambient light from the scene. And all is automatic, you simply don't have to worry about it. This comprehensive guide will walk you through all the aspects of the software from simple functions to complex 3D stereoscopic operations.
